Yeah! u need to put in the command sets on the PIX .
First step you would like to put would be the nat and global commands.
Second you would need to specify the routes for the dmz.
Pls let me know if you owuld like to know the syntax of the command.

Most likely, you need to check the access-list applied to your inbound DMZ
interface and permit tcp port 80. You also need to verify your nat commands
and global commands are set for dmz network too, if you are nating them.

You can have multiple NAT statements. NAT 0 will stop nat for whatever

The PIX is extremely versatile.

You can put your mail server on the inside but I would suggest putting a

your basic configuration looks like it will work just fine, Mo, except for a
few details that you'll want to implement - you have default pointed to

to avoid asymmetrical routing, you'll want anything that comes in via s1/1:0

Another rough answer: Ok, the DMZ deals with a 3 part firewall. Basically,
there is a LAN that hangs off of your firewall that contains your servers

A demilitarized zone (DMZ) is to protect your publicly reachable servers behind
the firewall. The difference between the more common scenario with two

I think Thats not true..!!DMZ is a region which is which a seperate

DMZ stands for demilitarized zone. It usually means that you are can put a
